Evaluating the Spatial Resolution of Flight-Simulator Visual Displays

摘要

This paper documents a technique for assessing the spatial resolution of visual display systems like those currently used for flight simulation at the Air Force Research Laboratory (AFRL), Mesa, Arizona. The introduction defines spatial resolution, and how best to apply the concept in the context of visual display evaluation. The measurement technique is described in detail, as are the CCD-based light measurement device and the techniques developed to calibrate it. Typical spatial resolution data are presented for a variety of display systems. The various steps required for data analysis, and suggested methods for implementing these steps using standard applications programs are presented. The computer programs used to generate and display the test patterns and to estimate spatial resolution are described and are available from Defense Technical Information Center (DTIC).
